| 摘 要： | 利用TM+SPOT影像融合数据对甘肃省定西县2000年到2001年土地利用和土地覆盖进行遥感调查,分析研究一年来该县土地利用结构,尤其是坡耕地退耕还林、还草的变化状况,客观评价定西县一年来的生态环境变化。初步实现了对区域生态环境变化的动态监测,为黄土地区退耕还林还草、生态环境调查及动态监测提供了可行的方法。

| Abstract: | The fusion images of TM and SPOT data were used in the study of land use and land cover of Dingxi county between 2000 and 2001. The changes of land use structure, especially those of cropland reforested and regrassed slope in the last year were analyzed to estimate the changes of environment of this county. Investigation and survey of regional environment was realized preliminary. Some feasible methods were put forward for investigation and dynamic monitoring of environment and reforesting and regrassing in loess plateau. |
